IMPROVEMENT IN PILE AND POST-DRIVERS. y

' The Schedule referred te inlthese Letters Patent and making part ofthe same.

I, N OAH HAVERMALE, of Canton, in the county of Fulton and State ofIllinois, have invented certain Improvements in Pile and Post-Dri-vers,of whiclrth'e following is a. specification. v

The natnreoi` my invention consists in providing a. suitableirame-workthatcan be loaded and hauled upon an ordinary wagon.

To the frontend of the frame two guide-posts are to any angle, andproperly braced when set up.

To the cap is attached the main line, which passes downward, and'suspends a m`ovable pulley, to which is attached the shipping-hook,which raises and drops the hammer. The line passes from the movablepnlley over one fixed to the cap, and thence to a windlass or otherpower. Y The shipping-hook is so constrncted'thai-,by means 'oifa cord,the hammer is let fall from any desired ele- The construction of theframefwork, the connection of the hammer, and the ease lwith which theweight is discharged at any height, make this machine peculiarly adaptedto the driving `of piles for highwaybridges `:or coffer-dams, or .theposts of an ordinary post-and-board-fence.

Figure 1 is aperspectivc elevation` of a pile and l post-driver. Figure2 is a side elevation of the shipping-hook.

VFigure 3 is an edge elevation of the draft-bar of the yshipping-hook. Y

Figure. 4 is avertical section, showing compound guide-arms'.

' Figure 5 is a front elevation of hammer, guide-arms, and-the foot of'one post. r

i General Description.

fill mortises in sills L, to which they are connected by suitablehinges, V.

Of any required weight I make the hammer H, cast with mortises toreceive the wooden guide-arms i) b, which have a slot i-n each end towork up and down On one side of' the hammer these arms have, on theirfront edges, a movable section, a, turning vertically npona bolt, theouter end of the section forming projection cast upon the hammer andabutton, c, upon the upper side of arm. (See igs. 4 and 5.)

Of 'suitable size and metal I makethe draft-bar A, as shown in figs. 2and- 3, having the vlever-hook I pinned'within the lower-endof thesides, and connected to the jointed lever I, that is pinned between thesides of the draft-bar above the joint, and then bent-upward, andterminating in an eye, in which is fastened the cord K. The joint of thelever I sets slightly toward the bar A, and the weight rests upon theAset-screw or pin J, that is secured to a plate riveted between thesides of the bar.

When the machine is to be used for driving piles for a bridge, properfalse work is made, about the height thepiles are to be when driven.Then the frame of the driver is removed from :the wagon, set on thefalse work, and properly leveled. If necessary, a sub-sill is placednn'der the -front end, extending far enough on either side toallowbracing from the ends of the sub-sill to the rings Z Z." The cap Yis placed upon its tenons, and the tenons of the braces X X are entered.The guide-posts W W are then raised to a right angle with the'sills bymeans of the braces It R, their upper ends being bolted to posts. Thentheir lower ends are to be bolted to S S of the windlassframe. Placethehookof the movable pulley M into G, the eye of the hammer-,fand draw itby the windlass to the platform U, and put in theshipping-hook. Whentheguide-arms b b are adjusted, the sections a a being raised Yso as toopen the slotsl raise the hammer,ix the arms in their places, close theslots, and fasten the sections by putting the inner lends down behindthe projections on hammer until they touch the bottom shoulder ot'projections, and secure themthere by turning the buttons c c. The pilebeing ready, raise the hammer, by means of the windlass, to any desiredheight. Then pull on the cord K until joint in I is straightened, andthe hammer discharged. If 'the height from which the blow is to bedelivered is determined, tie the cord K at the proper length to theframe, and the hammer will be dischargedf If it is desirable to drivethe piles at any inclination, as for a entier-dam, shorten the coupling0f the braces R R at their lower ends, as desired, bringing the top of Winward, and proceed as before stated.

When the machine is to be used for driving fenceposts, it is made ofsuitable size, remains upon the wagon, which is driven on the desiredline of fence,

posts W,guidebars D, braces X, cap Y, braces R and S, posts T, windlassP, rope O, land pulleys M and N,

when combined and arranged in the manner shownY and described, and forthe purpose set forth.
